ESD protection is often overlooked in hobbyist designs. Proper shielding and routing, as well as cheap ESD protection diodes, can make a world of difference, in a products lifetime, especially in applications with inductive loads.

you might be surprised how much you can do with a simple spark gap.
a grill lighter or modified milty zerostat can easily inject faults, albeit more manually and less precision than one of these timed devices. but it's also an order of magnitude or two cheaper...

I used this to EMP pulse a locked processor to gain access and extract flash memory from it.
Gave a talk at hardwear.io this year on it. YouTube live stream here: https://youtube.com/live/0tkdst3JE0g

Are there any affordable open source projects in the opposite direction?
I’ve built a rather complex robot with Nema steppers. Now something is messing with the control board and causing the CPU to glitch. Physically apart from the robot, the CPU board works fine for weeks. It also has a completely separate power circuit with optocouplers. So my guess is that it might be the power supply or one of the motors emitting electromagnetic interference. But how would I measure that?

Let's hope someone doesn't put on a bigger "antenna" on one of these and start frying electronics from a distance.
